Mean time between service incidents (MTBSI) is measured from when a configuration item (an item involved in the delivery of a service that is managed in the configuration management database) starts working until it next fails.
The essential structural component of a configuration management system is referred to as a configuration item (CI). Individual pieces of hardware or software are examples of CIs. The identification, change management, status accounting, and audits are key components that the configuration-management system implements and makes possible in order to manage the life of the CIs. With the help of this system, problems brought on by a lack of testing and incompatibilities with other CIs are to be prevented. Any piece of machinery or component that is tracked via a device record in Configuration Management might be considered a CI. The complexity, size, and kind of CIs vary greatly. Any object or procedure found in the Service Desk application, for instance, is documented as a CI.
